In accordance with the present invention.

and rising from the center of the bowl is a post carrying a wheel rotatable on a vertical axis and to which may be attached. by a series of other posts or uprights carried 'by the channel arms and each serving as a guide for the respective end of a rock lever having connection to the pistons or plungers of the pumps.

overriding the wheel so as to maintain it in the horizontal positionand receive the thrust imparted to the wheelby the pump levers.

Furthermore, the wheel is provided on its under surface withv a circular undulatory orcam member for imparting rocking movements to the pump levers, which latter are provided with rollers to reduce the friction between the cam surfaces and the levers. The cam surface is so constructed as to impart numerous movements to the'pump piston for each revolution of the wheel, and a the undulatory cam surfaces are so timed with relation to the pump levers that when the crown. portion of a cam is in engage ment with one end of a pump lever thevalley between two adjacent cams is then in engagement with the opposite end of the lever.

' angles to the arms 5, so that the arms 5 and I (3' are disposed about the bowl in approximately ninety degree relation. The outer .and' 20, respectively, each provided with a suction pump 21, 22, respectively. It will rights 8 to 11. Said uprights are made fast to respective arms 5 and 6 by angle plates 8 in part constituting covers for the channels 0 and 6. The stem 7 has an axial continuation 7 of smaller diameter constituting a pivot for a wheel 12 of a diameter to be encircled close to its periphery by the uprights 8 to 11. Each upright carries a roller 1.2 in overridlng relation to and in contact with the marginal portion of the 7 wheel, so that the Wheel is held to the approximately horizontal position against lifting forces and the pivot 7 is relieved from side or bending strains.

Fast to the marginal portion of the under face of the wheel is an undulatory or cam ring formed with a circular series of alternate summits or valleys representing a relatively large number of separate cams.

Traversing the post '7 below the wheel 12 are two rock levers 15 and 15 carried by pivots 16 and 16 respectively. These levers are made with arms of equal length and one is disposed above the other where passing through the post 7 The outer ends of each lever 15 and 15 carry pump rods 17 extending into the pumps 19 and 20 and while the customary. Each lever and 15 adjacent to the cam ring 14 carries rollers 24 thereby greatly reducing any friction which :might otherwise. occur when the cams engage the respective levers. r

Fast to the wheel 12011 top of the latter is asweep 13' and being thus located is entirely out of the way of any of the pumping structures. To this sweep one or more draft animals be attached or the sweep may be taken as representative of any means of pewter to the wheel to rotate it.

assumed that the wheel 12 is beingrotated by any suitable means, it remains 15 in a substantially horizontal plane by reason of the engagement of therollers 12 with the upper surface of this wheel. The cam ring I H beingin engagement with the rollers 24:

of thelevers15 and 15 causes an oscillation of these levers since, as will be understood, the cams" are so disposed or timed in action that when the crownjof one cam is in engagement with the roller 24: of a pump lever the diametrically opposite end of said lever'is then in a valley between two adjacent canisiof the cam ring. The arrange mentpermits' the employment of a circular series of cams of such length and number that in each revolution ofthe wheel each pump piston is reciprocated a relatively' large number of times and the pumping progresses with a commensurate speed. All

tendency to move the levers l5 and 15 sidewise by the cams of the cam ring 14 is prevented by passing these levers through elongated slots25 in and arranged lengthwise of the uprights 8 to ll,these slots be ing of. sufficient length to permit the rocking of the levers 15 and 15 The whole structure is very readily supportedat the mouth of the well or other container of water by beams 26 underriding the bowl or receptacle 23. I

The whole structureis of extremelysimple form requiring but few parts and is 'readilyapplie'd to or removed from a well I or c1stern and constitutes an efliclent struc- I ture for the purpose which may be set up ortaken down with a minimum of labor and oasis of t'n'is'jiat iit maybe obtaine d f r may be readily transported from" place to place. V

The invention in its practical embodiment is not of necessityoconfined to any exact conformity with the showing of the drawings, but such changes and modifications may be made as are within the scope of the up pended claims;

Having thus described my invention, what i I claim as new and desire to secure by Letthe uprights being longitudinally slotted and the pump levers extending through and carrying pump rods adapted to the pumps,

guided by the slots, a horizontally disposed wheel mountedon the post and rotatable on an axis longitudinal of the post, themargin of the wheel being adjacent to the uprights, a roller carried by eachupright in overridmg engaging relation'to the upper surface of the wheel adj acent' to its edge, a cam ring carried by the under surface of the wheel in position to engage the pump levers adjacent to the uprights, and said pump levers there being provided with rollers in the'path of the cams, and means for imparting rotary movements to the wheel.

2. A pump structure comprisingacen tralized bowl or receptacle, channel arms radiating therefrom, pumps carried by the channel'arms, a cam wheel carried by and mounted abovethe receptacle, uprights car; ried'by the radial arms/and provided with rollers engaging theuppe'r face of the cam wheel, and pump levers extending through and guided by the uprights and in turn e11 gaged by the cam wheel.
